The state of the art in marine battery energy storage

Our vision is to bring high quality, safe and concurrently cost-effective battery systems to the marine industry. To this end, AYK, using lessons learned from our years of experience, dating back to the first marine type approved battery, has developed several battery models to address the whole spectrum from high power to high energy applications.
